Application filed April 11, 1914. Serial n5. 831,121.

To all whom it may concern:

Be it known that l, GARY B. SMlTH, a citizen of the United States, residing at Chicago, in the county of Cook'and State of Illinois, have invented a new and useful Machine for hL-Iaking Bed Fabric, of which the following is a specification.

The device forming the subject matter of this application is a machine for making bed fabrics of that general type which consists of parallel chains of links connected by cross ties.

One object of the present invention isto provide novel means whereby, after the wire from which the link is made, has been advanced and released, the wire will be suddcnly and positively retracted before the wire is severed, thereby insuring a proper concatenation of the links.

Another object of the invention is to provide novel means whereby the rollers of the wire feeding mechanism will be rendered inoperative, simultaneously with the rendering inoperative of a grip which, being mounted upon a slidable cross head serves to advance the stock or wire.

Another object of the invention is to improve the driving mechanism whereby various portions of the machine are actuated.

' It is within the scope of the invention to provide means whereby, at the will of the operator, certain bending instruinentalities may be disposed in adjusted positions, thereby to vary the length of the link.

The invention contemplates the provision of novel means for moving the chain of links forwardly.

One object in view in the present invention is to improve the assembling mechanism and another object is to improve the means whereby the cross ties are clenched. onto the parallel portions of the chain of links when the latter is upon the holding drums.

It is within the scope of the invention to improve generally and to enhance the utility of devices of that type to which the present invention appertains. I

lVith' the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without de' parting from the spirit of the invention.

In order to understand in a general way the operation of' the machine herein disclosed,-Fig.'36 andFig. 27 may be referred to. As shown in Fig- 36. ,a length of wire 29 is bent upon itself as shown at 92 and is cut off as at 93to form a staple shaped ele ment, the ends of which are turned up to formihooks94. Referring to Fig. 27, the side portions of the staple shaped element are crowded together asvshown at95 and i eyes 96 are formed therein. An ,eye 98 existing at one end of the link is assembled with the hooks '94 and thus a chain is formed. The chain is carried around a pair ofupright drums in a plurality of convolutions as depicted, for instance in Figs. 11 and 30. Cross ties 125 of the general shape shown in Figs. 17 and 18 are fed downwardly and are connected with the links of I the chain. The hooks at the ends of the cross ties 125 are clenched down, and thus a completed fabric is formed.

The machine herein disclosed resembles in many particulars, the devices shown in my co-pending applications Serial Nos. 728,915 and. 755,100 (Patents No. 1,114,402 and 1,116,506). Since sundry portions of the machine shown in this application have become a part of the prior art, the description in this application may be shortened accordingly, reference being bad to the disclosure above identified.

In carrying out the present invention there is provided as shown in Fig. 2, a supporting structure 1 comprising a table 2. Mounted upon the table 2 is a frame denoted generally by the numeral 3 and including as clearly shown in Fig. 3, a guiding eye 32. The frame 3 supports a wire feeding mechanism comprising shafts 4 and 5, the shaft 4- preferably being spring depressed, to maintain in coacting relation, feed wheels 6 and 7 on the shafts 4t and 5 respectively. As shown in Fig. 4, the frame 3 includes a lateral extension 8 from which project guide rods 9. Mounted for a limited reciprocation on the guide rods 9 is a carriage 10, retracted by a tension spring 11 attached to the carriage and to some fixed element, such as the frame 3. The carriage 10 is provided with horizontal straightening rolls 12 and vertical straightening rolls 14.

Superpose'd upon the table 2 is a bed plate 15 equipped near its rear end with supports 16 which are shown clearly in Figs. 3 and 4-. Mounted to swing on the supports 16 is a trip 17. Journaled in the supports 16 is a rock shaft 18 carrying a movable member or arm 19. When the rock shaft 18 is actuated, the movable member or arm 19 is adapted to be brought into a common plane with the upper face of the trip 17, for a purpose which will be set forth hereinafter. Upstanding from one end of the rock shaft 18, as shown in Fig. 3, is a crank arm 20 pivoted to a rearwardly extending pitman 21 operatively connected with a lever 22 fulcrumed onthe table 2. The pitman 21 carries, as shown in Fig. 1, a wedge 23 lying beneath the spring depressed shaft 4 of the feeding mechanism.

The bed plate 15 is equipped with a guide 24. in which is mounted to reciprocate a cross head 25 carrying a pivoted grip 26, the cross head being provided with a stop 27 which prevents the rear end of the grip 26 from dropping too far downwardly. Mounted on the rear end of the grip 26 is an agljuslable catch preferably taking the form of superposed nuts 28.

The wire from which the links are fashioned is denoted by the numeral 29. The wire 29 passes through the guiding eye 32 and is formed into a convolution 30, the wire passing between feed wheels 6 and 7 prior to being formed into the convolution, and passing also through the lateral eXtension 8 on the frame 3. As shown at 31 in Fig. 4, the wire is extended again through the extension 8 and is passed between the straightening rolls 1212 and 1414 on the carriage 10. Thence, the wire passes between the forward end of the grip 26 and the cross head 25, as shown in Fig. 3.

The operation of the structure as thus far described is as follows: When the shafts 4 and 5 are driven, the wire is advanced to form the convolution 30. When the cross head 25 moves in the direction of the arrow- A in Fig. 3, the nuts 28 on the grip 26 ride up onto the trip 17 and engage the rear end of the trip. Then, as the cross head 25 is moved in the direction of the arrow B the wire 29 will be advanced. because, when the trip 17 is swung upwardly by the action of the nuts 28, the grip 26 will have been tilted so that it will have engaged the wire 29 and bound the same against the cross head 25. Now so soon as the cross head 25 is started back in the direction of the arrow A, the hold of the grip 26 on the wire 29 will be released, because the wire is relatively stationary. Therefore, as the cross head 25 is reciprocated in the direction of the arrows A and B, the wire 29 will be advanced by a step by step movement. WVhen the wire 29 is advanced as above described, the slidable carriage 10 will be advanced also, owing to the frictional hold of the straightening rolls 12 and 14 upon the wire 29 and as the carriage 10 is advanced. the spring 11 will be put under tension. hen the cross head 25 starts to move back in the direction of the arrow A and when the hold of the grip 26 on the wire 29 is released, as hereinbefore clescribed, the carriage will be drawn back sharply and suddenly by the action of the spring 11, effecting a corresponding abrupt retraction of the wire 29. The object in thus retracting the wire 29 will be alludedto at the proper point in the description of the invention. At times it is desirable that the cross head 25 should reciprocate freely without advancing the wire 29. When such an operation is desired, the lever 22 is tilted,

advancing the pitman 21 and rotating the rock shaft 18 until the arm 19 thereon is alined with the upper surface of the trip 17, this operation being clearly understood from Fig. 3. Then the upper surface of the arm 19 on the rock shaft 18 is alined with the upper surface of the trip 17, the abut ment nuts 28 on the trip 26 will slide from the trip 17 onto the arm 19, without looking behind the rear end of the trip 17 and tilting the trip. Consequently, the grip 26 will not be tilted sufiiciently to cause it to engage the wire 29 and bind the wire against the crosshead 25. It will now be understood that by manipulating the lever 22, the parts of the machine will be so positioned that the cross-head 25 may be moved back and forth in the direction of the arrows A and 13 without advancing the wire 29. In this con nection it is to be noted that when the pitman 21 moves in the direction of the arrow B, the wedge 23 on the pitman, engaging beneath the spring-depressed shaft 4 of the wire feeding means, will raise the said shaft and elevate the feed wheel 6 out of operative relation to the feed wheel 7 and off the wire. Therefore, the feeding of the wire 29 is stopped, not only so far as the cross-head 25 is concerned, but also so far as the feeding mechanism 6-7 is concerned.

From the description as thus far given it .will be understood that the wire 29 is fed forward in predetermined lengths, intermittently.

I will now describe the means whereby the cross-head 25 is moved to and fro, and whereby the feeding mechanism 6-7 is actuated. Extended transversely of the frame of the machine and journaled therein is a shaft 33 provided at one end, as shown in Fig. 2, with a belt wheel 34 about which is trained a belt 35, operatively connected with a drive shaft 36 journaled on the supporting structure 1. Noting Figs. 10 and 2, it will be seen that a U-shaped crank 37 is at tached to one end of the shaft 33, the crank being connected by a link 38 to a rod 85 (hereinafter referred to in detail) the rod 85 being attached to the cross head 25. Thus,

when the shaft 33 is rotated, a reciprocating movement will be imparted to the cross head 25 through the medium of the crank 37 and the link 38. The shaft 4 of the Wire feeding mechainsm is actuated from the shaft 33 by means'of a belt or sprocket chain 39 operatively connecting these elements. After the wire 29 has been advanced, the next step is to put a bend therein, as indicated at 92 in Fig. 36. The mechanism for fashioning the bend 92 will now be set forth in detail. FiXedly held upon the frame work of the machine, but adjustable longitudinally of the machine, is a support 40, held in place by means of a set-screw 41, en gaging the machine frame. Journaled for rotation in the support 40 is a bending shaft 42. A curved or approximately U-shaped member 43 has one leg inserted into a central bore in the shaft 42, the other leg of the member 43 being fixed in a hole in the support 40, to prevent the U-shaped member 43 from turning when the shaft 42 rotates during the bending operation. The shaft 42 is provided with a transverse slot 44, extended part way therethrough. That leg of the U-shaped member 43 which is located in the bore of the shaft 42 extends across the slot 44. The wire is fed forward by the action of the cross head and the free end of the wire passes through the slot44 in the bending shaft. Then, when the bending shaft is rotated, the forward end of the wire 29 is swung backwardly, to form the bend 92 shown in Fig. 36. In order to procure an intermittent rocking movement in the bending shaft 43, the same is provided 4 49 andthe shaft 33 are intermeshing, interrupted pinions 50.

The construction above described is such that when the shaft 33 is rotated, a reciprocating rotary movement will be imparted to thebending shaft 42 through a gear-train comprising the pinions 50, the supplemental shaft 49, the pitman 47, the rack bar 46 and the'pinion-45 on the bending shaft.

Thenext step, referring to Fig. 36, is to cut off the length of wire at the point indicated at 93, sothat a staple shaped element is formed, the free ends of the staple shaped element being turned up to form hooks 94. Journaled for rotation in the machine frame is a horizontally disposed transversely extended cutting and bending shaft 51. A rocking or reciprocating movement is imparted to this shaft 51 by means of a rack formed on the under face of the rack bar 46. Noting F ig, 5, it will be obvious that whenthe shaft 51 is rotated, the same will cut off the wire at the point indicated by the reference character 93 in Fig. 36 and turn up the ends of the staple shaped element to form hooks94. The bend made at 94 is formed around a shiftable fulcrum rod 52, mounted to slide longitudinally in the cutting and bending shaft 51. In order to retract the fulcrum rod 52 and to withdraw the operative'end thereof from the hooks 94, the fulcrum rod 52 is connected as shown j in Fig. 4 with a lever 53, fulcrumed interoff as shownat 93, the bend 92 of the wire is advanced and elevated along the inclined guide 55 by the action of the cross head 25. The bend 92 of the wire then drops down over the end of the inclined guide 55, and is interengaged with the hooks 94 of a pie ceding link which has been substantially completed and is held between an anvil 72 and a die 73, to be described in detail hereinafter. It is at this time that the springretracted carriage 10 becomes operative, and before the wire is cut off as shown at 93, draws the wire sharply back, thus engaging the bend 92 with the hooks 94 of a completed link, and positions the body portion of the wire properly,;to be cut by the action of the shaft 51, the arms of the staple-shaped element being of equal length, and no waste resulting, because the back bent end is not cut a second time. During the time that the bend 92 is being interengaged by the hooks 94 of a completed link, the bend 92 is held down by a compression member 57, pivotally supported as shown at 56 and drawn downwardly by means of a retractile spring 58, connected as indicated at 58 (Fig.

2) with any fixed part of the machine, it being understood that the particular means for securing the lower end of the spring 58 is immaterial.

Noting particularly Fig. 37 it will be seen that the compression member 57 is provided in its bottom with a relatively wide slot 708 which receives the bend 92 of the wire. At the top of the slot 708 is formed a restricted slot 709. At the other end of the slot 708 are inwardly inclined faces 710. As the substantially completed link is pulled back by the bend 92, the hooks 94 of the completed link are forced toward each other on opposite sides of the inclined guide 55 by coming in contact with the faces 710, and are thus held by projections 711, located on opposite sides of the inclined guide 55. Inorderto prevent a lifting of the completed link when the die 73 is raised, a spring arm 60 bears upon the completed link, as shown in Fig. 5, the arm 60 being secured at one end as shown at 59. The compressive effort of the arm 60 is regulated by means of a set-screw 61, engaging a spring 62 which bears upon the arm 60. As depicted in Fig. 7, the operative end of the arm 60 is slotted as shown at 60, to straddle the link. When the bend 92 is made, and when the free end of the wire is swung back as shown in Fig. 36 said end of the wire passes out of a slot in the side of the adjustable support 40 and in the machine frame, into which slot the wire has been fed previous to the bending operation. A closure or gate 63 is mounted to move toward and away from the slot in question, and acts as a guide when the looped end 92 of the wire is advanced and before the wire is cut ofi as shown at 93. The gate 63 may be slotted to receive supporting screws 64 and is actuated at the proper time by means of a bar 67 having pins 66 adapted to ride in inclined notches 65 in the gate 63. The bar 67 is actuated through the medium of an eccentric pin 68 mounted on the end of the cutting and bending shaft 51, and adapted to coact at the proper time with a notch 68 in the bar 67 Reference has been made incidentally hereinbefore to the die 73 and the anvil 72. These elements are carried by a fixed but longitudinally.adjustable support 69 which, as shown in Fig. 4, may be connected with the frame work of the machine by set screW. and slot unions 70. The support 69 is adjusted and held in adjusted positions by means of a set screw 71 engaging the sup-. port and a portion of the machine frame. Owing to the fact that the support 69 may be adjusted in the direction of the length of the machine, and owing to the fact that the bending shaft 42 may be adjusted longitudinally of the machine by moving the support 40 through the medium of the set screw 41, the length of each link may be varied. Thus, it is never necessary to cut a link in order to accommodate a bed frame ofany specified length, it being possible to adjust minutely the length of each link made, so that when all of the links are concatenated into a chain, the chain of links will be of the proper length. The anvil 72 is mounted on the adjustable support 69 and the die 73 is slidably mounted thereon for vertical movement. The means for procuring a vertical reciprocation of the die 73 will be under stood best from Figs. 8, 2 and 10. Pivoted to the lower portion of the die '73 is a link 74 connected with. a lever 75, fulcrumed intermediate its ends at 76 upon the machine frame. The rear end of the lever is connected with an angular link 77, having a common mounting with the link 38 upon the crank arm 37.

From the foregoing it will be obvious that the gear train for actuating the die 73 comprises the shaft 33, the crank 37, the link 77, the lever 75 and the link 74.

Noting Fig. 9 it will be seen that the die 73 is provided with a plurality of fingers 78, the inner faces of which are inclined as shown at 79. Located between the pairs of fingers 78 are removable, adjustable prongs 80, shown in Fig. 8. The anvil 72 is equipped with recesses 81 adapted'to receive the fingers 78 when the die 73 descends. The function of the inclined fingers 78 is to crowd the side arms of the link together, as shown at 95 in Fig. 27, the prongs serving to form eyes 96 in the link. Adjacent its ends, the die 73 is provided with lugs 82. These lugs 82 act to clench down the hooks 94 as the die descends. As shown inFig. 8, and as indicated at 97, one-half of one prong is cut away. This feature is desirable, because the particular prong in question is compelled to pass into theterminal eye 98,

in which the hooks 94 of a preceding link are already engaged. After the several links have been concatenated into a chain as above described, the chain is advanced, and the function of the rod will now be apparent, and this rod, as indicated in Fig. 10 is actuatedby the cross head 25, which in its turn, is actuated by the link 38, the crank arm 37 and the shaft 33. As shown in Fig. 2, a support 86 is adjustably attached to the rod 85 as at 87. Pivoted to the support 86 is a dog 88, constrained by a spring 89 which extends between the dog and the support, to move in a recess 01' passage 83 (see Fig. 3) formed in the element 69. Overhanging the end of the passage 83 is a platform 84 and located adjacent the other end of the passage is a lifting cam 90. When the rod 85 is advanced, the dog 88 engages the chain of links in the recess 83 and advances the chain. The rod 85 has a longitudinal movementwhich is considerably in excess of the longitudinal movement which it is desired to impart to the chain of links, and, therefore, inorder to render the dog 88 effective throughout a portion only of the stroke of the rod 85, the platform 84 and the lifting cam 90 are provided, the construction being such that after the rod 85 has moved forward to a certain extent, the dog 88 will ride up on the lifting cam 90 as shown in Fig. 3. When the rod 85 is retracted, the dog 88 will ride up onto the forward edge of the platform 84, the forward edge of the platform preferably being beveled to facilitate this operation. In order to prevent an accidental back-drag on the chain of concatenated links, a resilient back-stop pawl 91 is provided, the free end of the back-stop pawl entering the recess or passage 83 and engaging the chain of links, the free end of the back-stop pawl being so fashioned that it will prevent a backward movement of the chain without impeding the forward movement thereof.

The description as thus far proceeded with has pointed out how the links are fashioned and interengaged to form a chain. It now remains to point out how the cross ties are applied and how the completed fabric is taken care of. Comparing Fig. 11 with Fig. 1 it will be seen that a supplemental frame 99 is located adjacent the main supporting structure 1. The supporting frame 99 is provided adjacent its ends with bearings 100 which may be adjusted by means of set screws 101. Carried by the bearings 100 are shafts 102, the upper ends of which are. mounted in bearings 103, con trolled by set screw 104, the bearings and the set screws being mounted in a tie bar 105. This tie bar 105 may be of any desired length, and one tie bar may be replaced by another, depending upon the length of the fabric which is to be formed. Carried by the shafts 102 are drums 106 provided with sprocket .wheels 107 around which are trained sprocket chains108. The drums106 are equipped with circumscribing grooves 109. U f Y {The invention includes an upright guide bar 110 shown in detail in Fig. 26, the guide I bar 110 being secured to the sprocket chain 108. Mounted on the supplemental frame 99am tracks 111 adapte'd to be engaged by a roller 1.12 on the guidebar 110, asclearly shown in Fig. 26.

The invention includes a support 113,

'formedin a' plurality of sections,-there being fingers 114 struck from the support 113,

these fingers 114 engaging the edges of the guide bar 110,as clearly shown in Fig. 25,

the construction being such thatthe support 113 may move vertically upon the guide bar. Each section of thesupport 113 is provided with a roller-115. The roller 1'15 isadapted to pass beneath a cam bar- 116 mounted onthe supporting frame 99 at the front thereof as shown in Fig. 11. Thus,

as the guide bar and the support move circumferentiallyof the drums 106, the support 113 will be caused to move downwardly on the guide bar 110 as these elements pass along the front of the-supporting frame 99. On the back of the supporting frame 90 there is a channeled guide 117, shown in Fig. 12. This guide is adapted to receive one roller 115 on the support 113 as the same moves across the back of the supplemental frame-99. The bar 110 is prevented from being depressed, bothatthe front of the frame and at the back thereof, by reason of the fact that the roller 112 of the guide bar engages" the tracks 111, On the guide 110 there is a spring finger 178 which interlocks with openings 179 in the support 113, disposed below the fingers 114 on the guide. Thisspring finger178, serves to aid insupporting the member 113, but its hold therepins. 120;

- the .main supporting structure 1.

on is not strong enough to prevent downward movement of the support 113 when the same is actuated by the cam bar 116. In itsopposite edges, the support 113 is provided with fingers-118and 119, as shown in Figs. 23 and 11'. Adjacent the fingers 119 are Referring to Fig. 2 it will be seen that a supplemental frame 121 is mounted on Supported by the frame 121 is a machine 122 for making the cross ties. This machine 122 depicted by the reference numeral 125. The

curved delivery arm'124 comprises a relathe next lower run of the link chain.

tively fixed part 701 and a laterally movable part 702, reference being had particularly to Figs. 38 and 39. The fixed part has a depending flange 703 and the movable part 702 has a depending flange 704, said parts and their respective flanges being hingedly connected as at 7 05. The movable part 7 02 is swung to the left in Figs. 38 and 39 by means of a spring 706 secured to the flange 703 and bearing on the flange 704, the

parts 701 and 702 abutting like a rule joint hinge to limit the swinging movement of the part 702 and its flange to the left under the action of the spring 706. Thefiange 704 carries an offset cam strip 707.

Referring to Fig. 2, the completed chain of links is carried over suitable guide pulleys 127 and is carried forward and to the front of the assembling mechanism, as shown in Flg; 11. The chain of completed links is lodged in the grooves 109 in the drum 106, so that the chain passes around and around the drums as the latter are rotie bar 105 may be of any length, each section of fabric may be long enough to make more than two complete beds. It has been stated hereinbefore that the completed cross ties made in the machine 122 traverse the delivery arm 24. Now as the chain support 113 moves along, the same strikes the cam strip 707 and swings the parts 7 02 of the (lelivery arm to one side, after which the spring 706 restores the part 7 02 to the posi tion shown in Fig. 38. The cam strip 707, it will be understood, serves to space the chain support 113 from the part 702 and prevents the chain support from sweeping the cross ties off the part 702 of the delivery arm. From the delivery arm 124, the crossties drop onto certain convolutions of the chain of links which passes around the drums 106, although, if desired, the cross ties 125 may be removed manually from the I delivery arm 124 and be connected with successive convolutions of a chain of links. When the cross tie drops onto a chain of hnks, the hook at the upper end of the cross tie 125 is engaged with one strand or convolution of the link chain, as shown in Fig. 17, the hook at the lower end of the cross tie, however, not yet belng engaged wiith 11 order to couple up the hook at the lower end of the cross tie with the lower run of the chain, a mechanism is provided which will now be described in detail, reference being had particularly to Figs. 17 and 18. Fulcrumed to swing upon the supplemental frame 99 is a lever 128 with which is con nected a link 129 united with a connection 130, operatively connected with a pedal 131. Projecting from the supporting frame 99 is a bracket 132 to which is pivoted a-link 133 united by a pivot element 138 with the link 129 and with an arm 134 having a slot 135 receiving a pin 136 on the bracket 132. In the bracket 132 is formed a slot 137 adapted to receive the pivot element 138. At the extremity of the lever 128 is formed a spring finger 139. As shown in Fig. 19, a notch 140 is formed in the extremity of the spring finger 139. The arm 134 terminates in a fork shaped head 141, notched in its extremities as shown at 142 in Fig. 20. The lever 128 and the pedal 131 are raised by the action of a spring 700, shown as extending between the support and the arm 134, although the spring may be located otherwise and still exercise its function.

Comparing Figs. 17 and 18, it will be understood that when the pedal 131 is de pressed, the lever 128 will be drawn downwardly. The cross tie 125 will be engaged in the notch 140 of the spring finger 139 and the latter will tend to swing the cross tie 125 inwardly so that the hook on the lower end of the cross tie engages with the chain. When the link 129 is moved downwardly, the arm 134 will be advanced and the fork shaped head 141 will act as a brace for the lower run of the chain, the hook at the lower end of the cross tie 125 entering the notches 142 of the fork 141 and snapping into the chain. By the operation above described, the cross tie 125 is connected with adjacent runs of the chain of links. It now remains to clench the hooks at the upper and lower ends of a pair of cross ties around the chain of links, as shown in Fig. 16. The mechanism for efiecting this result will now be described in detail. Located between the drums 106 is a reciprocating carriage 144 supported for movement upon guides 143 carried by the supporting frame 99. Supported by the carriage 144 is a channel shaped guide 145, shown in Figs. 15 and 13, this guide receiving the hooks at the upper ends of the cross ties, while the hooks at the lower ends of the cross ties are being clenched, as will be understood clearly from Fig. 15. Mounted to the rear of the frame 99, as shown in Figs. 1 and 15 is a post 146, provided on its forward face with an inclined guide 147. Attached to a hammer 151 hereinafter described in detail, is a spring finger 148 adapted to lock over the lower run of a chain of links, as clearly shown in Fig. 15. The free end of the spring finger 148 engages with the inclined guide 147 and tightens up two adjacent cross ties 125, between the spring finger 148 and the guide 145, as clearly shown in Fig. 15, so that the inner ends of these cross ties will be adapted to be clenched. The clenching mechanism involves an anvil 149 mounted in the post 146 and held in adjusted positions by means of a screw 150. Coiiperating with the anvil 149 and slidable in the frame 99 transversely thereof is the hammer 151, hereinbefore mentioned, the inner end of which is recessed, as shown at 152 in Fig. 16, so as to effect a proper clenching of the inner ends of a pair of cross ties around one strand of the chain of links. Noting Fig. 14 it will be observed that a link 153 is pivoted to the hammer 151, the link 153 being connected by means of a pivot element 154 with a link 155 on the frame, pivoted to a link 155 having a loose connection with a lug 157 on the carriage 144. It will now be obvious that when the carriage 144 is moved in one direction, the hammer 151 will be advanced, to coperate with the anvil 149 and to clench the adjacent ends of a pair of cross ties, the hammer being retracted when the carriage is moved in an opposite direction. The carriage 144 is actuated from the rod 85. Note particularly Figs. 21 and 22. With the rod 85 is pivotally connected a crank arm 158 forming a part of .a rock shaft 159 journaled in suitable bearings, the rock shaft 159 including an upstanding arm 160 connected by means of a link 161 with a lever 162 mounted as shown at 163 intermediate its ends, for swinging movement, there being a link 164 which connects the upper end of the lever 162 with the carriage 144.

Noting particularly Fig. 14, a spring arm 165 is mounted on the carriage, the same terminating in a finger 166 the point of which enters one link of the chain. It will now be obvious that when the rod 85 is reciprocated as hereinbefore set forth, reciprocating motion will be imparted to the carriage, the chain of links being advanced and the drums 106 being rotated. A spring arm 167 projects from the post 146. This arm 167 serves to hold one strand of the chain of links in operative relation to the guide 145 on the carriage 144, it being obvious that when the support 113 passes. between the guide 145 and the post 146, the chain of links would be held apart from the guide 145 in the absence of the finger 167. A spring arm 168 on the post 146 serves to hold the chain of links against the carriage 144. Projecting from the carriage 144 is an arm 169 terminating in a head 170 which is slotted to receive the chain of links and to hold the same in proper position to be engaged by the finger 166 on the end of the chain driving arm 165. Attached to the post 146 is a relatively long spring arm 171 which bears upon the chain of links adjacent one of the drums 106. In order to prevent the chain of links from being dragged backwardly by'the action of the carriage 104, a latch 172 is mounted to slide inthe frame 99 and is normally retracted by means of a spring 173 connected with the latch and with the frame. In order to advance the latch- 17 2, a wedge or cam 174 is mounted "on the carriage 144 and coeperates with a roller 175 on the latch. At its outer end, the latch 172 is slotted as shown at 176 in Fig. 34 so as to straddle the chain of links andto prevent a retrograde movement there- 'In Fig.28 of the'drawings, a modified means is shown for actuating the clenching hammer. In this figure, the hammer 180 is mounted to reciprocate in the supporting frame, as before stated and is provided with asquared end 181 slidable in the supporting frame. A compression spring 182 abuts against the frame and against a shoulder on the hammer to advance the hammer. Mounted on the carriage is a cam strip 183 beveled to coact with a roller 184 on the hammer. An arm 185 is pivoted to the carriage, one end of the arm being swung inwardly by the action of a spring 186. As the carriage moves to the right, the cam strip 183 engages the roller 184 and effects aslight initial retraction of the hammer 180, in order to free the hammer from the fabric, as the fabric is moved forwardly. As the carriage moves to the right, the roller 184 moves along the cam strip 183 and ultimately raises the inner end of the arm 185, putting the spring 186 under tension, the roller 184 passing beyond the left-hand end of the arm 185. Then, as the carriage .moves to the left, the roller 184 traverses the outer edge of thearm 185 and retracts the hammer 180, putting the'spring 182 under compression. Ultimately, the roller 184 rides off the right-hand end of the arm 185 and then the hammer 180 is advanced suddenly and forcibly by the action of the spring 182.

In Figs. 31, 32, 30, 29 and 33, a modified form of the invention isshown. figures of the drawings there is shown a supporting platform 187, corresponding to the platform 121. In this form of the invention, the assembling mechanism is given an overhead support, instead of being sup.

In these ported from underneath, by means of the frame 99. Mounted on the support 187 is a frame 188 having guides 189 on which the carriage 190 moves, the carriage being actuated by a rod 191, corresponding to the rod 85, the rod 191 being operatively connected with the carriage 190 by means of a pin and slot connection 192. The hammer 193 reciprocates in the frame 188 and is actuated by a mechanism 194 hereinbefore described. Secured to and upstanding from the support 187 is a curved post or arm 195 carrying the adjustable anvil 196. The guide 197 corresponding to the guide 145, is now fixed on the post 195 instead of being mounted on the carriage. The carriage-supported spring arm which draws the connected cross-ties downwardly, to tighten the same before they are clenched, is shown at 198 in Fig. 32, the operation of this detail having been gone into fully hereinbefore. The guide arm on the carriage is illustrated at 199 and the back-stop latch is shown at 200, the same being actuated by a cam strip 201 on the carriage. A spring arm 202 is mounted on the post 195 and exercises the same function as the spring arm 168 in Fig. 14. The chain feeding arm on the carriage is shown at 207. Brackets 203 are mounted on the support 187 and are connected with the upper ends of shafts 204 carrying drums 205 connected by sprocket chains 206. A spacing rod 208 connects thebrackets 203 as shown in Fig. 29 and carries nuts 209 adapted to engage the brackets. One bracket, as shown in Fig. 29, is pivoted as at 210, so that the bracket in question may move when the nuts 209 are adjusted on the rod 208. Owing to this construction, the chains 206 which pass around the drums 205 may be tightened.

In the form of the invention under discussion, the support 113 shown in Fig. 11 is'not employed, the fabric being made in a continuous length, as shown in Fig. 30. Since the lower ends of the shafts 204 are free, the completed fabric in a tubular form, moves downwardly, and as the length of the tube of fabric increases, the lower end of the fabric may be pulled to the front or to the rear, out of the way.

The operation has been dealt with step by step, and a lengthy review thereof at this place is unnecessary. It may be stated, however, that through the medium of that portion of the machine which is depicted. in Fig. 3, a length of wire is advanced and bent back upon itself to form a hook. The hook is cut off from the end of the length of wire and the ends of the hook, which has now assumed a staple shape, are bent up. The elements thus formed are concatenated into a chain and by the action of the die and anvil mechanism shown in Figs. 8 and 9 are spaced as shown in Fig. 27. The chain thus cross-ties are clenched onto spaced convolutions of the chain.
